1NF to 3NF

ORIGINAL STARTING FORM AC_NUM = aircraft number
MODEL = model of the plane
MANUF = manufacturer of plane
TYPE = type of plane (single engine etc..) AC_CHARGE = aircraft charge per hour

DATE = date flown
TYPE = type of instruction
HOURS= hours flown

TTAF = total time on air frame
TTEL = total time on left engine
TTER = total time on right engine
CUST = customer number

given this information I neet to convert from first normal form to third normal form. I am having trouble understanding partial and transitive dependancies. How do I break this down when the composite primary key is CUST, HRS, DATE and AC_NUM? Received on Wed Nov 22 2000 - 23:16:27 CET
